Notes:
In Zone 15 under jack pine and aspen. This is a rare sighting in November (and not in the thick of that moss!) but they’re unmistakable with those gills.

Interestingly, if you put this obses coordinates into Google Maps you can access Google Street View images of Zone 15, and, by navigating around, even see what the borders of Zones 12 and 13 looked like before they got trashed.
